Unit testing and CI

Module goal: test firmware logic on the host computer, and have CI check every change.

Status: alpha (experimental) · Approximate time: 140 minutes

Every lesson has content, examples you can run on your computer, practice with a solution, a check for understanding, and a lab. The course code runs and has been checked on a computer; the on-board labs are still waiting for a teaching trial.

Lesson	Topic	Time
c-found.m06.l01	Unit tests on the host	70 min
c-found.m06.l02	CI for firmware	70 min

End-of-module checkpoint

• Have at least five unit tests that run on the host, and prove that at least one of them can genuinely fail.
• Plant at least three kinds of bug in your logic, and have the tests catch every one (none survives).
• Have a CI workflow that runs tests, checks formatting, runs static analysis, and compiles for Cortex-M on every pull request.
• Have a pull request where CI turned red because of a deliberately planted bug, as proof the checks can actually fail.
